Mobil1 & Redline - 75W90 gear oil
Spectro - Heavy duty Primary Crankcase Oil

I liked Spectro & have only used Redline for 5k miles. I'm not sure if I will still have Redline when I get to the track again.

The manual shows the tranny should be filled with 1 qurt, one bottle, with the bike on a level stand the fluid level will be at the bottom of the clutch starter gear, just as the manual says. Remember your torque wrench when putting the drain plug back. Sometimes the gasket has to be replaced. Thread dope, locker, tape is not needed, this is not a twinkie.

If the square gasket gets gunk on it then the gasket stretches & is a pain to re-use & it is easier to repalce.
